More PWI Math Problems (Twilight Temple)

[アイドンノウくん]

Guess it would be fun to do some math related to PWI, especially for those who like math and PWI.
So, here's the problem:

Ancient Evil: Lethal Vengeance
Assuming now Lethal Vengeance has the following drops distribution:
Drops                                                                                                            Probability
1 Ancient Devil's Soul  +  3 Ancient Devil's Horn + 6 Stone of Sacred Temple            - 3%
1 Ancient Devil's Soul  +  3 Dust of Devil            + 6 Stone of Sacred Temple            - 3%
3 Ancient Devil's Horn  + 3 Dust of Devil            + 3 Stone of Sacred Temple             - 9%
                                                                     9 Stone of Sacred Temple             - 85%

Suppose you want to collect each type of mats dropped by Lethal Vengeance. How many times do you need to kill Lethal Vengeance on average?

Answer: 20 times

Nope, too much lower than the correct answer.

don't get me wrong but something makes me think that you're a secret agent, checking the intellect of mmo players

You are pretty close to the answer, but it is still lower than the answer. Good job because it is so far the closest one to the  correct answer.

21, yes I'm just guessing blindly

Lol...Interesting and creative thought! Ofc there's always possibilities, it's just the matter of how high the chance is I am a secret agent spying on the intellects of mmo players...So, do you think how high the chance is?
